Data and Estimation programs for "Financial Incentives and Fertility" by Alma Cohen, Rajeev Dehejia, and Dmitri Romanov
----------------------------------------------------------------------------------------------------------

This is a readme file that explains what files are included in the directory and how the data necessary to run the programs could be obtained. 


A researcher seeking the data will need to contact Mr. Yoel Finkel, deputy director of the the Israeli Central Bureau of Statistics (ICBS), phone: +972-2-6592201, email: yoelf@cbs.gov.il or Prof. Danny Pfefferman, Government Statistician of the ICBS, phone: +972-2-659-2210, email: danny@cbs.gov.il. 
The Data is restricted and can be worked on only at the Israeli CBA in Jerusalem.  


Once the data is obtained, the programs can be used to generate the Tables that appears in the paper. 

To generate the tables one needs the following datasets:
- Fertility_data.dta -- this is the full data set, in Stata 11 format.
- CAnewborn.dta -- this data include information about child allowance levels during the period we study.
- npv_ada_ar1_lag.dta -- alternative present value of expected subsidies for three alternative models of expectation formation: adaptive expectation, autoregressive expectation, and AR(1).

The do file that merge the datasets and provides the Tables is: Financil_Incentives_and )fertility_do_file.do

The definitions of most variables should be self explanatory from their names. For most of the variables definitions can be found in Appendix B of the paper.
